title: 1-Ethyl-2-phenyl-3-[2-(tri-methyl-sil-yl)ethyn-yl]-1H-indole.
abstract: The title compound, C21H23NSi, was synthesized by Sonogashira-type reaction of 1-ethyl-3-iodo-2-phenyl-1H-indole with tri-methyl-silyl-acetyl-ene. The indole ring system is nearly planar [maximum atomic deviation = 0.0244 (15) Å] and is oriented at a dihedral angle of 51.48 (4)° with respect to the phenyl ring. The supramolecular aggregation is completed by weak C-H⋯π inter-actions of the methylene and phenyl groups with the benzene and pyrrole rings of the indole ring system. The methyl groups of the tri-methyl-silyl unit are equally disordered over two sets of sites.
